CORE FOR LINING- CONVERTERS.

Specification of Letters Patent.

Patented Sept. 1, 1914.

Application filed April 28, 1913. Serial No. 764,120.

To all whom it may concern Be it known that I, J ULES BAILLOT, a subject of the King of Belgium, residing at Montmagny, Province of Quebec, Canada, have invented certain new and useful Imrovements in Cores for Lining Converters; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apperta-ins to make and use the same.

The invention to be hereinafter described relates to the manufacture of converters.

In order to more clearly disclose the construction, operation, and use of the invention, reference should be had to the accompanying drawings forming part of the present application.

Throughout the several figures of the drawings like reference characters designate the same parts.

In the drawings: Figure 1 is a front view of the converter, partly broken away to show the interior; Fig. 2 isa central, vertical, cross section through the detachable bottom plate; Fig. 3 is a central, vertical, cross section through the body of the converter, inverted; Fig. 4: is a lateral cross section online H of Fig. 3; and Fig. 5 is a like cross section on line 5--5.

The main objects of the invention are to provide a simple, efficient, durable, economical, and compact sectional removable core, together with means for readily and easily positioning the same inside of a con-- verter to enable easy and quick molding of the lining of the converter wall, directly within the converter.

Referring to thedrawings in detail, 1 indicates the outer wall of the converter, and 2 a top plate detachably connected thereto by means of perforated ears on the wall adapted to be passed through openings in the top plate, suitable wedges being driven through the ears to force the top plate snugly into position. To the inner face of the top plate are removably secured, two cooperating core members 3 and 4. These members, together, constitute an approximately conical core extending in an inclined direction upwardly through the elbow bend or angle to the top. Each of these core members is solidly secured to the top plate 2 by means of bolts 5 and 6 passed through the plate and threaded into their ends. Consequently, when the top plate is fastened in position, the core formed by members 3 and 4 exactly occupies the upper part of the interior of the finished converter. The two members 3 and a are mounted to have longitudinal movement relatively to each other so that the member 3 may be disconnected from the top plate and drawn out after the molding operation is finished, as will later appear. As shown in the drawings, this sliding connection is by cooperating dovetail mortise and tenon on the respectivemembers. This insures a proper guiding of the member 3 while being withdrawn and is, therefore, the preferred arrangement. It is clear, however, that various other sliding connections may be used.

The lower end of the member 3 is provided with projecting dowel pins 7, or the like, and a screw eye 8. The screw eye serves as a connection for. withdrawing the core, and

the dowel'pins act as guides for the bottom elliptical core section 9 which completes the core, as a whole. The upper end of the section 9 is provided with sockets to receive the dowel pins, as clearly shown in Fig. 3, and a screw eye 10 for withdrawing it after the molding operation has been completed.

The bottom plate 11 is secured to the wall 1 in the same manner as the top plate, but is very differently formed. It is deeply concaved or dished to, receive a thick filling or layer of highly refractory infusorial earth or a plastic composition of the same.

In carrying out the invention, the converter is inverted and the core members 3 and l are positioned, all as shown in Fig. 3. Then brace bars 12 are placed in position to properly maintain the free ends of the core members in their exact central position. Preferably, these bars 12 are provided with heads removably seated between pairs of angle irons projecting from the inner face of wall 1. The bars are of such length that their inner ends will barely, or not quite, touch the outer surface of the upper ends of the assembled core members 3 and 4. So, when the assembled members 3 and t are in position, the brace bars 12 are slid into position between their angle irons and act to accurately center the upper ends thereof. Then the lining material such as refractory infusorial earth, composition, or the like, is filled in and solidly packed in the space between the wall 1 and members 3 and 4:. WVhen it has reached the free end of the members 3 and 4, the brace bars will be removed, the member 9 will be positioned, and

the space between it and the wall 1 will be similarly filled. When the filling is properly set, the member 9 will be withdrawn, the bolt 5 turned out of member 3 and member 3 withdrawn in the same manner and directionas member 9, and, finally, the top plate 2 disconnected and the member 4; withdrawn with it in the opposite direction. In this manner, the converter may be quickly, easily, and thoroughly lined in an economical and efiicient manner.

It is thought that the construction, operation, and use of the invention will be clear from the preceding detailed description.

Changes may be made in the construction,

arrangement, and disposition of the several parts of the invention without in any way departing from the field and scope of the same, and it is meant to include all such within this application wherein only a preferred form has been disclosed.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is: p

' 1. In combination, two core members, means for slidably connecting the, same, another core member connected to the lower end thereof, and centering means disposed between said core members and said wall.

2.111 combination, two core members,

means for slidably connecting the same to form a frusto-conical core section, another core member connected to the lower end of said frusto-conical core section and extending at an angle to the longitudinal axis member detachably connected to said plate,

a second cooperating core member detachably connected to said plate, means for shdably connect ng said core members, and

1 a core member seated upon the free ends of said connected core members.

4. In combination, a top plate, a core .member detachably connected to said plate, a second cooperating core member detachably connected to said plate, means for 'slidably connecting said core members, a core member seatedupon the free ends of said connected core members, and means for centering said connected core members.

In witness whereof-I have hereunto set my hand in the presence of two witnesses. JULES BAILLOT. Witnesses:
